摘　　要：确定了不锈钢方管电子束钎焊的工艺参数,并利用扫描电子显微镜和能谱分析仪,对电子束钎焊试样的显微组织进行了分析。结果表明,选用合理的工艺参数,可获得良好的钎焊接头。钎料区主要是固溶体组织。母材区除了奥氏体组织外,存在铜元素的扩散。Electron beam brazing parameters of stainless steel quadrate tube were decided.The microstructure of the brazed joint was investigated by means of a scanning electron microscope and an energy spectrum analyzer.The results showed that the good joint was obtained by using proper parameters.The microstructure of brazing filler metal is mostly solid solution phase.Other than austenite,copper element dissolution was found in material.
